ARCTIID.-E. 247 



broader ; hind wings ample, rather elongated ; thorax narrow ; 

 abdomen short. 



1. E. jacobseae, Z. Expanse, \\ to 2 inches. Fore wings 

 smoky black with a red stripe and two red spots ; hind wings 

 red, without markings. 



Antenna black, threadlike, with a few oblique, hardly- 

 perceptible bristles ; head, thorax and abdomen velvety black ; 

 forewings rather triangular, narrow at the base, very broad 

 behind, with the costa slightly curved, apex and hind margin 

 rounded, and dorsal margin straight ; smoky blackish-grey 

 with a light crimson or rather cinnabar-coloured stripe from 

 the base near the costa to just before the apex, where it is 

 slightly expanded ; another stripe of similar colour from the 

 base runs along the dorsal margin tapering to a point beyond 

 the middle ; and near the hind margin are two roundish 

 crimson spots, one just below the apex, the other above the 

 anal angle ; cilia smoky-grey. Hind wings rather long and 

 very ample, regularly rounded at the apex and hind margin ; 

 bright crimson, scarlet, or cinnabar, edged along the apex 

 and hind margin with smoky-grey ; cilia smoky-grey. The 

 bright colour of the hind wings agrees with that of the stripe 

 on the dorsal margin of the fore wings and renders it very 

 inconspicuous. Female rather larger and stouter, otherwise 

 similar. Underside an exact copy of the upper; body and 

 legs deep velvety-black. 



Usually very constant in colour and markings. One, in 

 Mr. Bond's collection, has the red colour replaced by bright 

 yellow. It is said to have been taken long ago in Horning- 

 sea Fen. One recorded in Devon had the hind wings blotched 

 with yellow ; and another from Brighthampton is said to 

 have had the markings of the fore wings ochreous while the 

 hind wings were buff. In rare instances the dark colour of 

 the fore wings becomes light olive grey, or the hind wings 

 darkened with smoky grey. Such specimens are in Mr. S. 

 Webb's collection ; and also one devoid of the dorsal crimson
